[TrinityCore][3.3.5a] Animation bug with converted models from later xpacs?

[Teryaki]

Good evening Ownedcore!

I am just posting to ask if this bug can be fixed with animations and converted models from later expansions. From time to time some of my models just randomly stop moving all together and get stuck in a still state.



Not much you can see from a picture ofc, but the monkey isn't moving at all. If I delete then add him again, his animations resume. Then after awhile they just stop all together again.

Problem with the model? DBC problem that I overlooked?

Thanks for the help!
